Exploring Biltmore’s Historic Orchid Collection

Biltmore’s love affair with orchids goes back more than a century, when George Vanderbilt was first planning his grand estate in Asheville, NC.

With some 25,000 species and 100,000 cultivated varieties, orchids comprise one of the two largest families of flowering plants, growing in every ecosystem except Antarctica. Discover the colorful history behind Biltmore’s orchid collection and how our team cares for the alluring specimens year-round.

Orchid Mania in the Victorian Era

Though orchids have been a beloved flower since Roman times, it wasn’t until the early 1800s that the enchanting plants became extremely popular in Britain seemingly overnight. With elite Victorians seeking them out as status symbols, the demand grew and many people became obsessed with acquiring orchids for their collections, generating a fad known as “orchidelirium,” or orchid mania.

Private collectors and “orchid hunters” traveled far and wide, often under dangerous circumstances, to search for the finest exotic orchids on nearly every continent and ship them back to Europe at exorbitant prices.

Fortunately, by the late 1800s when George Vanderbilt was planning his grand estate in Asheville, orchids were more readily available from nurseries and no longer required sending collectors on arduous journeys.

Filling the “Orchid House”

Conservatories and glass-roofed garden rooms filled with private plant collections remained popular among wealthy estate owners in Europe and the United States throughout the late 19th century. Naturally, George Vanderbilt followed this trend with the construction of Biltmore’s Conservatory and the Winter Garden room of Biltmore House.

For Biltmore’s collection, landscape architect, Frederick Law Olmsted, specified that 800 orchids, comprising more than 30 varieties, should be purchased for furnishing the Conservatory’s “orchid house.” In archival photographs, orchids can also be seen adorning tablescapes in the Winter Garden surrounded by palm trees, providing a lush and exotic space for the Vanderbilt family to relax and entertain guests.

Today, Biltmore’s orchid collection contains close to 1,000 plants. In the collection are award-winners recognized by the American Orchid Society and some of the very same varieties contained in Olmsted’s original list.

Caring for the Orchid Collection

While much of the work to care for Biltmore’s orchids happens behind the scenes, the effort is always evident. No matter the time of year, our team rotates blooming plants onto display inside the Conservatory for guests to enjoy their irresistible beauty.

A typical week among the orchids includes fertilizing and watering the collection and then tending to the display areas in the Conservatory. If severe cold weather strikes during winter months, team members may have to take extra precautions to protect the plants, including running auxiliary heaters in all of the greenhouses and moving the plants into warmer spaces overnight.

Quick Tips for Orchid Care at Home 

Of all the orchids in Biltmore’s Conservatory collection, you may be wondering which is the most popular with our guests. According to our garden team, guests are very drawn to Phalaenopsis, or “moth orchid,” likely because it is one of the more recognizable varieties that they may have at home.  

You don’t have to be a professional gardener to enjoy the beauty of orchids. Biltmore’s Orchid Horticulturist, Marc Burchette, shares these tips for successful orchid growth at home: 

G – Give your orchid a bright east or north-facing window with little to no direct sunlight.  

R – Regulate temperatures to avoid exceeding 90 degrees Fahrenheit during the day or below 55 at night. 

O – Only water plants when they are completely dry to avoid overwatering.  

W – Maintain humidity levels between 50 to 80 percent. You can use a gravel-filled tray partially filled with water if needed.  Plants should not sit in water. 

T – Treat with a balanced fertilizer (10-10-10 / 20-20-20) at 1/4 recommended strength weekly during the growing season.  

H – Handle repotting every 2 to 3 years or when new root growth is observed; use a well-draining mix.

Creating Curb Appeal in front of Biltmore House

To say that the summertime curb appeal in front of Biltmore House veers toward the dramatic would be accurate! Towering palm trees flank the front door, all of them carefully arranged in terracotta pots sturdy enough to keep the contents secure. For plantings this huge, their containers can measure up to 40 inches tall and 50 inches wide.

Some of the containers in front of Biltmore are replicas made in Impruneta, Italy, the same town in which the home’s original pots were made in the late 1800s. For the reproductions, the faces and garlands were matched with the ones on the original pots.

This year, Biltmore gardener Todd Roy created the plant design for the containers at the front of the house, the terrace that crosses the facade, as well as the pots at the base of the Rampe Deuce, across from the house.

Guests often ask Todd and his cohorts on the horticulture team questions on how best to get the Biltmore look in their home gardens. Here are some of Todd’s favorite tips for creating dazzling container gardens at home.

“Thriller, Filler and Spiller”

To achieve a balanced container, Todd says to design with these basic components.

• “Thrillers” are the upright, tall component.

• “Fillers” are medium-height, middle-area plants.

• “Spillers” are the plants that hang over and around the edges of the container.

Select plants with similar watering needs
Consult the plant tags for watering requirements so you are choosing plants that share the same maintenance schedule.

Keeping Track of Biltmore Gardens Railway

Please enjoy this archived exhibition article.

Twice a year, Biltmore’s Conservatory is home to Biltmore Gardens Railway, an elaborate G-scale railway with locomotives and rail cars weaving through the historic greenhouse’s exotic botanicals and miniature replicas of estate landmarks – even one of the Conservatory itself! A second railway display is located in Antler Hill Village where trains travel past replicas of the Eiffel Tower, London’s Tower Bridge, and other European landmarks visited by George Vanderbilt during his world travels. 

Biltmore Railway House
“Luxuriant” bamboo, as Frederick Law Olmsted called it when planning George Vanderbilt’s gardens and grounds, was harvested and used as the roofing material on the Biltmore House replica. Grapevine was also collected and fashioned into Biltmore’s iconic gargoyles.

Scaling down Biltmore House

Working from original floor plans, drawings with elevations, and photographs of Biltmore House and other estate structures, a team with Applied Imagination constructed the Biltmore replicas using natural materials they gathered from estate grounds. The result is a stunningly accurate version of Biltmore.

Some fun facts to consider:

1,700 – The number of hours it took to construct the 10-foot-long replica of Biltmore House, compared to… the 6 years it took to build the 250-room Biltmore House in the late 1800s.

6 – The number of artists it took to build the scale model of Biltmore House, compared to… the 1,000 workers it took to build Biltmore House in the late 1800s.

5,000 – The number of tons of Indiana limestone used to build Biltmore House in the late 1800s, compared to… the 25 types of items harvested from estate grounds to create replicas of Biltmore House and other buildings. This included horse chestnut, magnolia leaves, hickory nuts, lotus pods, bamboo, pine cone scales, acorn caps, winged bean, star anise, grapevine, honeysuckle, ash bark, oak bark, pine bark, elm bark, hickory bark, eucalyptus leaves, day lily stem, rose of sharon, cedar branch, walnuts, stewartia, wisteria, turkey tail fungus, and contorted Filbert.

Artists from Applied Imagination suited up in waders to snip a few treasures from the Italian Garden pools. The lotus pods growing there were just too perfect to pass up, and ended up in the creation of the Stables.

Inside the Conservatory

6 – The number of separate railroad tracks running through the Conservatory carrying locomotives and rail cars around the buildings. The trains cross bridges and trestles on varied levels and through multiple rooms.  

8 – The number of estate building replicas in the Conservatory. 

7 – The number of artists it took to create all of the replicas in the Conservatory.

3,745 –The number of combined hours it took to construct eight estate building replicas for the Conservatory exhibition.

Attention to detail is paramount, even down to the conductor’s facial features!

Tracking progress

8 – The number of buildings in the display at Antler Hill Village. 

1,050 – Amount of railroad track in feet required for the displays.

1 – Amount of weeks to install Biltmore Gardens Railway at two locations on the estate.
